SPECIFICATION formin part (if Letters Patent No. 692,901, dated February 11,1902.

Application filed August 6, 1901. Serial No."71,1(l1. (N 0 model.)

:To all whom it may concern:

Be it known that I, JOHN NEWTON PHIFER, a citizen of the-Unitedfitates, residing at Shumway, in the county of Efli ngham and 5 State of Illinois, (whose post -r'office address'is Shumway, 'Illinois,) have invented certain new and useful Improvements in Electrical Generating-Machines; and I do declare the following to be afull, clear, andexact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings,'and to the letters and figures of referencemarked thereon, which form a part of: this specification.

My invention relates to electrieal-frictiongenerating machines, and comprises an.apparatus for drying and purifying the air in such machines. It is well known that to produce .good or the best results in suchmachines it is necessary that the air within the casing be dry. It is also well known that operation of the machine causes the production of ozone, which impairs the further generation of electricity. It is therefore essential that the ozone be expelled and fresh air introduced.

The object of my invention is to construct an apparatus which will dry the air within the casing without in any manner interfering with the operation of the machihe.'-

A further object is to provide an apparatus which will-not leak off current from the machine'". v f A-further object is to construct an apparatus for the purpose referred to the principalparts of which are without the casing, so that there will be no, occasion for opening the casing to effect the purpose of my apparatus.

With these and other objects in view the 'trated in theaccompanying drawings, in

Figure 1 is a vertical section of'the appara-u .tus.. Fig. 2 is a section on the 1ine2 2 of Fig.0

1, showing my apparatus inf plan.

Referring more. particularly to the drawlogs, the casing of a machine, of the character stated is indicated'at The form and construction thereof are immaterial to my invention. It is usually arectangnlar box with is contained. 1 have considered it unnccessary to illustrate a machine,-as the same has no connection with my invention and may be of the Holtz or other type.

An opening in the floor of the casing is provided with a nipple, 7, preferably made of glass and threaded on the portiomprojecting below the bottom of the floor of the casing.

To this nipple, by means 'of hard-rubber coupling 8, is connected a hard-rubber pipe 9, the lower end of which passes through the a top of a glass jar e and within'an inch or two of the bottom thereof. The jar is surrounded by a freezing mixture, 'su'ch as salt and ice, contained within a wooden pail 11, in

which the jar is placed. Communicating with the jar, through the top thereof, is a hard -rubber pipe 12, which is fitted to a sheetsteel pipe 13, provided with an enlargement- 13 forming a hot-air chamber, .theheat for which is supplied by the flame of a lamp 14 inproximity thereto. Theother'end of the steel pipe is fitted to a'hard-rubber' pipe 15 at one end thereof.' The other end of the pipe communicates with the chamber 16, preferably extending at a right. angle to the pipe,

and. in the chamber isafan 17, the shaft of with the interior ofi'the case through a coup- The coupling ling 20, fitted to a nipple 21. is of hard robber and thenipple ofrglass, similar-to the nipple and coupling heretofore described, and the nipple fits a hole in the floor of the case and communicates with a glass pipe 22, which extends vertically within the casing to a point near the toprthereof. In the top of the casing, above the glass pipe, a valved opening 23 is made.

' In operation if the electric current from the machine be defective on account ofdampness the lamp is lighted or the fan started, which causes-a current ofair throughth'e pipe 22, i the valved opening 23 being closed. This in-- ,ducesja current of moist air from the bottom oft the casing through the pipe 9 into the glass jar. 10, where the moisture in the air is eon-"' den sedibyreason of the freezing mixture 'sur rounding the jar. The air then passes through the pipe 13, where it is heated, and thence or by reason of the fan through thepipe 22 into the casing.- A circulation of the air is thus maintained during the operation-of the machine or as long as may be necessary. Instead of the freezing mixture surrounding the glass jar dry calcium chlorid or similar hyfrom the air passing through the same.

groscopi'c substance may be placed within the jar for the purpose of absorbing the moisture If by use of the machine the air within the casing becomes charged with ozone, so that the operation of the machine is affected, the valve 23 may be opened and the air within the case expelled by means of the lamp under the hotair chamber, which will heat the air and cause same may be operated while the apparatus is attached and working. I

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-- 1. An air-drying apparatus for electrical generating-machines comprising an insulated pipe communicating with the interior of thecasing of the machine and adapted to conduct the air therefrom, 'means to deprive the air so conducted of its moisture, and an insulated pipe adapted to return the airinto the casing.

2. An air-drying apparatus for electrical generating-machines comprising an air-pipe communicating with the interior of the casing, an insulating coupling between the pipe and the casing, means to exhaust the air from the casing through the pipe, means to extract moisture from the air so exhausted, means to then heatthe air, and an insulated pipe adapted to return the air so heated to the casing.

3. In an air-drying apparatus for electrical generating machines, in combination, a casing for the machine,-a vessel in which air may be deprived of its moisture, an insulated pipe connecting the casing and the vessel, another pipe leading out of the vessel having means to heat the air therein, and a fan adapted to force the air into the casing.

4. In an air-drying apparatus for electrical generatingnnachines, in combination, a casing for the machine, an opening in the bottom thereof, an insulated pipe connected with said opening, a'vessel adapted to receive air from said pipe, means to extract moisture from the air in the vessel, a heating-chamber, a pipe communicating between the vessel and the chamber, a pipe communicating from the heating-chamber to the interior of the casing, and a fan adapted to force the air through the p e.
